Very very Noisy Switch - XS724EM
Recently bought a new Switch to our office to be able to run 10Gbit. This one: XS724EM - 24-Port 10-Gigabit/Multi-Gigabit Ethernet Smart Managed Plus Switch And I think the fans are going insane...
It does sound like we've got similar environments in terms of temperature, 10G clients etc. but opposite manifestations of a fan issue. It could be faulty hardware or it could be a quirk of the way this firmware version interprets the sensor data.
Either way, the periodic fan ramp-up does not appear to be intended behavior.
In my case, there's some doubt as to whether some fans will selectively spin down under standard ambient temperature in an attempt to prioritize noise reduction over cooling. This is what I've been told directly by Netgear technicians, even though it seems bonkers. But that approach would make your XS724EM's jet engines the very thing they're trying to avoid.
I'd call Netgear support, as your device should be fully warrantied, and ask them to replace it or issue firmware to correct the issue.
Another potential solution is for Netgear to give the admin more visibility and control over fan speeds and temperature. If you wouldn't mind, please upvote my recommendation to that effect.
I found a very simple solution to this problem. I placed an old and small oscillating fan I had in my garage next to the intake vents of the switch and turned it on and it worked. The outside box of the switch is much cooler and those dang fans are not constantly revving up :) The noise the oscillating fan is not much and is actually pleasant.
I've done a very similar thing by placing one of those cheap desktop USB-powered fans next to the switch's intake. It runs constantly but more quietly than the switch's internal fans and keeps the device markedly cooler.
This is a simple DIY solution but an inelegant one that should be unnecessary. This is a switch that's retailing for $2,200 right now. It's like buying a high-end luxury car and then having to strap a window AC unit to it because the cabin gets too hot.
I tried that USB-powered fan but it did not work for me. The oscillating fan is doing a great job at keeping the thing quiet and cool. I agree with you on this being unnecessary. Bye
